need help with viruses and adware

[evenifigoalone]

A little help...?
It looks like the adware that was on my laptop found it's way over to the desktop computer. Plus, keep getting notifications on start how the virus program blocked this or that.
I ran a full system scan, and then a boot scan. In all those found about four files and successfully got rid of them. Still got the notifications on startup, and the adware is still coming up on one of the regular webpages I visit (and have been visiting for years without issue).

Do I need to get a new virus program or something...? What I have currently is Avast.

You may also want to check what addons/plugins you have installed on your browser. Which browser do you use?

Could try installing and running a scan with Malwarebytes. It may find something the others missed.

Browser is Google Chrome

Okay, so here's what going on trying to use malwarebytes on the laptop (which it was already installed on), which runs Windows 7:

• I start in safe mode, open malwarebytes, it tells me it's outdated--I don't have networking on, so
• I try safe mode with networking--result, opening malwarebytes immediately shuts the computer off
• try opening malwarebytes in normal mode--another immediate crash
• uninstall malwarebytes--done successfully, but computer crashes (again) while I'm in the other room and is off when I come back in
• try opening safe mode--doesn't work, and Windows opens normally
• I restart computer and tell it to do Windows Repair--after a few seconds it tells me it couldn't find any problems......liar.

The laptop has already been infected for a while, btw. The stuff with my deskptop computer just started today.

Okay, was able to run Malwarebytes on the deskptop computer running Windows 8.1. It found 70 files, two of which were malware/trojans. Now that that's done, the popups seem to be gone.
But Avast is still warning me about two infections and two malware gens on startup.


...maybe now all I need to worry about now is that stupid laptop. Which doesn't even belong to me. And which I don't have a repair CD for since it came preinstalled. And which I can't afford to take to the computer repair shop again. RRRRGH!!
